On 1/3/13 returned to the same dyno with the above mods to test out the stage 2+ OTS 93 octane, PTF stage 2+ 93 octane, OTS E30, and PTF E30 maps. Unfortunately, with the holidays, we werent able to 100% complete (On second revision) the 93 octane map and nothing on the E30 maps. That being said, here are the results for at least the PTF 93 maps and at least OTS e30.

@eric@helix for another amazing FMIC that does an awesome job of keeping temps down. On stage one stock fmic, saw a 70 degree spike in temp during the pull on intake temps. For all the pulls today on the helix, saw only 10  15 degree increases in temp from start to end of pull. More evidence that a solid FMIC is a huge benefit for this car.

@Terry@BMS for the cheap AR Dps and DCI, fast and easy to work with as usual.

414/464? Great numbers but I have a hard time buying them... I hear about these numbers all the time but have never seen them on a dyno. A protuned 335i FBO with 50/50 E85 made like 380 on a dyno local to me.

These are from a dyno. Not sure how you have a hard time buying them. I don't find it hard to believe pro tuned cars are putting up low 400s on e85

Protuned on E85 he should be in the 430whp/490+wtq range. I was about to jump on the baselines for the stock tune numbers and cry foul that the dyno is optimistic, then I remembered that you have a 335is, lol. Nice numbers, right in line with what I'd expect to see given the mods/conditions.

Not saying it's not possible just a little bit hard to believe, the protuned cars that I have seen dyno in my area never made even close to that much power.

I think it's very believable on a DynoJet because I made 380hp/420tq on a Mustang dyno down here in Texas while it was still hot with 110+ IATs on a 1/2 finished E30 map before COBB came out with their OTS E30 map.

I am pretty sure that I will have a near identical setup soon and will try to replicate these numbers

stock fuel pump btw???

Unless you can keep your IAT's down during the pulls you'll be losing some power due to IAT timing corrections. Stock DME starts pulling timing just after 100*. This is why flash tunes have an advantage when running E85, that and the ability to advance timing past the stock timing curve.

The gain from adding E30 in comparison to the pro tune is HUGE .
Why such a big difference?
The E30 tune is just OTS right?

With e30 you can run a lot more timing and less boost taper than you can even dream of with just 93, protune or not. The fact that it's only a 20whp delta is a testament to how good the pro tune is. Let PTF get his e30 protune done and it'll be a nice jump over the OTS maps.

As your goals were more to lean on the safety side of things when tuning there's some more power locked up in the pump gas map any time you'd like us to push more out of it, and plenty more with a custom E85 blend map due to added octane and reduced EGTs like some others have mentioned

Sorry for the delays, was out to dinner.

Yes, it was the OTS running 2 gallons of E85 (was actually only 80% when I tested it) and 5 gallons of shell 93. The power bump comes mainly the timing. You can actually see it has less boost than the PTF stage 2. The AFR was inline with OTS stage 2 map, while the PTF ran lower.
